Answer: 4 x 10^12
Step-by-step explanation: first you distribute the powers into tens. Any multiply 10 to the eighth power to six, and multiply 10 to the -4th power to 1.5. After that you divide the first number in parentheses by the second number in parentheses. This answer on a regular calculator would be 4+12 zeros. Thus creating the answer 4,000,000,000. Which is, simplified in scientific notation, 4×10 to the 12th power.
